Thank you for viewing. This is a Yamaha tom clamp. It's a long-type ball mount and clamp for toms. The ball mount allows for flexible positioning of the tom. ■ Single tom clamp ■ Long rod: 120mm ■ Long pipe: 352mm ■ Pipe diameter: 22.2mm This is an accessory for the Yamaha Stage Custom Hip. It has only been taken out of the bag for photos and has not been used. I am selling it because I don't use it.
